for a good steering servo its better if you dont cheap out and get something that just works. You want at least .10 speed and 140oz of torque. Ive been running the airtronics 94359z servo since winter and i cant say enough about this servo. Never once gave me a problem, always provided awesome speed with a lot of torque. Its 129 dollars and worth every penny. Its got a built in heat sink to help prolong your servo's life. If you got the money definatly pick it up, if not sell something and pick it up lol. http://www.amainhobbies.com/product_...oducts_id=2454
